What You'll Learn
The fuel filter is easy to replace
The fuel filter in an FJ62 is easy to replace. It is not necessary to replace the fuel filter in an FJ62 unless it is on your PM schedule or you know it is clogged. The fuel filter can be replaced by simply unbolting the lines and bolting the new one in. However, it is important to note that some gas may leak when you unhook the old filter, and it may take a few extra cranks to start the engine back up. Additionally, the system is pressurized, so some gas may get on you during the process. Nevertheless, replacing the fuel filter is a straightforward task that can be completed without seeking professional help.
When replacing the fuel filter, it is recommended to first depressurize the system. This can be done by disconnecting the fuel line before the fuel filter and turning the switch to the 'on' position. It is also important to replace the belts and hoses, as well as all the fluids, before replacing the fuel filter. The belts in the FJ62 can be particularly challenging to replace due to the difficult-to-reach tensioners.
While replacing the fuel filter is a relatively easy task, it is important to exercise caution and follow the proper procedures to avoid any potential issues. Some mechanics recommend removing the fuel pump fuse or relay and letting the engine run until it dies. However, this method may not be suitable, as running out of gas with fuel injection can be harmful. Another approach is to clamp the hose with vice grips before removing the filter.
Overall, replacing the fuel filter in an FJ62 is a straightforward task that can be completed by following the steps outlined above. It is important to prioritize tasks and address the more critical issues first, such as replacing the belts, hoses, and fluids, before turning attention to the fuel filter. By following these recommendations, you can ensure a smooth and effective replacement process for your FJ62's fuel filter.

You will get some fuel on you when changing the filter
When changing the fuel filter on an FJ62, it is important to be aware that some fuel may leak. This is because the truck's system remains pressurised even when it is turned off, so you will need to be prepared for some fuel to escape when you unhook the old filter. This is not a major concern, but it is something to be aware of, and it is sensible to have rags ready to soak up any spilled fuel.
One way to minimise the risk of fuel spillage is to depressurise the system before you begin. This can be done by removing the fuel pump fuse or relay and letting the engine run until it dies. Alternatively, you can simply crack the bolts loose with the truck turned off, and only a small amount of fuel will escape.
If your FJ62 has been sitting unused for a long time, it is a good idea to replace the fuel filter. This is because the filter can become clogged, reducing the power of the vehicle and starving the motor of fuel. It is also recommended to replace the belts and hoses, as well as all the fluids, before moving on to changing the fuel filter.
The fuel filter on an FJ62 is not difficult to access, and the whole process of changing it is relatively straightforward. However, it is important to take appropriate safety precautions when working with fuel, including avoiding any open flames or sparks. By following these steps and being prepared for some fuel leakage, you can successfully change the fuel filter on your FJ62.

Depressurise the system before changing the filter
Depressurising the fuel system of an FJ62 is important before changing the filter to avoid spraying yourself with hot, highly pressurised fuel. Here is a step-by-step guide on how to do it:
Firstly, locate the fuel pump fuse, usually found in the fuse box under the hood. Remove the fuel pump relay while the engine is running, causing it to stall after a few seconds. Then, crank the engine for about 10 seconds to finish removing the pressure. This method may cause a loud and unpleasant noise, but it is generally safe.
Alternatively, you can simply wait overnight for the system to depressurise naturally. However, this method may not work for all vehicles, and you will still need to wear protective gear such as eye protection.
Once the system is depressurised, you can proceed to change the fuel filter. Place a pan or rag underneath the filter to catch any spilled fuel. Disconnect the fuel lines, unscrew the filter carriage, and raise it straight up, including the o-ring. Remember to have a catch pan handy as the fuel lines will drain.
It is also important to note that you should never clamp flex lines on an injected vehicle. Instead, pull the fuel pump relay or hit the inertia switch (fuel pump kill switch).

Don't forget about the copper washers
When changing the fuel filter on your FJ62, it's important to remember to pay attention to the copper washers. These washers play a crucial role in creating a tight seal and preventing fuel leaks. There are typically four copper washers, two on each end of the fuel filter, and it's essential not to lose or drop them during the replacement process.
The copper washers provide a better seal compared to the standard washers that come with replacement filters. They are designed to ""crush" slightly, similar to an oil pan drain plug, to ensure a snug fit and prevent leakage. If you happen to lose or damage the copper washers, it is not recommended to substitute them with steel washers, as this may lead to ongoing leaks.
To avoid losing the copper washers during the fuel filter change, it's a good idea to be cautious and keep them secure. You can also find replacements at dealerships or parts stores if needed. When purchasing replacements, ensure you get the proper size by either providing the part number or taking the old washers or the fuel line with you for reference.
Additionally, it's worth noting that the FJ62's fuel filter doesn't require frequent replacement. Unless you know it's clogged or due for a change according to your maintenance schedule, you can prioritise other maintenance tasks first, such as replacing belts and hoses, fluids, and addressing the front axle and brakes.
By following these recommendations and paying attention to the copper washers, you can ensure a successful and leak-free fuel filter replacement on your FJ62.

You can disconnect the fuel line before the fuel filter
Disconnecting the fuel line before the fuel filter on an FJ62 is a straightforward process, but it requires careful attention to safety precautions. Here is a step-by-step guide to help you through the process:
Before beginning any work on your FJ62, it is important to ensure that the engine is turned off to avoid any accidental ignition of fuel. The fuel pump fuse or relay can be removed to prevent any fuel injection while the engine is off. This is a recommended step to ensure safety during the procedure.
To begin disconnecting the fuel line, locate the fuel filter on the passenger side wheel well hump. It is a large black canister, and accessing it may require removing any obstructions, such as the rear anti-sway bar link brackets or the passenger-side shackle. Once you have clear access to the fuel filter, proceed to the next step.
Place a rag over the union, just like when opening a soda bottle, to catch any leaking fuel. You can also use a short piece of hose on the return line coming from the tank to control the fuel flow. Now, carefully loosen the bolts that hold the fuel filter in place. Have some rags ready to absorb any fuel that may leak out during this process.
After loosening the bolts, you can proceed to disconnect the fuel line from the fuel filter. Use the appropriate wrenches to carefully detach the line, being mindful of any residual fuel pressure. Once the fuel line is disconnected, you can continue with the next steps in your maintenance or repair procedure.
It is important to note that working with fuel can be dangerous, so always exercise caution and follow safety guidelines. Ensure proper ventilation and avoid any sources of ignition during the process. By following these steps, you can safely disconnect the fuel line before the fuel filter on your FJ62.
